If the code is not closing the connections, then close all the open connections properly so that you can save memory leaks in the code and save database memory. Sometimes, the number of cursors in the database exceeds the maximum limit, and as a result, the following error is thrown: java.
Before using an explicit cursor, you must declare it in the declaration section of a block or package as follows:. Before start fetching rows from the cursor, you must open it.
To open a cursor, you use the following syntax:. When you open a cursor, Oracle parses the query, binds variables, and executes the associated SQL statement. Hi Tom, Sorry for not being explicit. I was trying to mention that if we do a close within the procedure where we open the cursor , the cursor actually is closed. But, If we don't put a close in the procedure, the cursor is not closed even though the procedure has finished. But that does'nt happen. Also, if you could please let me know why do I get the other 9 records from the table, when I just do one fetch 5 times?
July 22, - am UTC. You would not expect the cursor to be closed -- else there would be NO WAY to return a result set from a stored procedure. I don't know what you mean by that last paragraph at all??? You fetched a row in plsql -- sqlplus fetched the rest? Which proves that the cursor is not opened. I can be sure that it is showing records from the cursor, because it shows only the 10 records that I selected while defining the cursor. I am just trying to understand what is happening here.
Please excuse my inexperience :. I'm really not understanding where you are going with this. If you left the cursor open, sqlplus gets it and prints it. If you close the cursor, sqlplus doesn't get it, cannot print it. If we closed input before leaving x -- foo would not be usable. Don't understand reader, July 22, - am UTC. I am a bit confused here. Hence we should be able to print the values from the global cursor at the SQL prompt.
Have I got something wrong here? Hi Tom, Here is the query that I ran on my database as the developer complained about getting ORA, but he is fixing his code and closing the cursors. But, the results of the queries are so different, can you explain why July 27, - pm UTC. A reader, August 17, - pm UTC. Tom, How can i know how much memory is used by each cursor. August 18, - am UTC. We know that we have to fix the application, but in the interim we would like to increase the cursors open to But, this is the feedback we got : "Each open cursor consume 2 to 5 MB of memory, depend upon execution work.
Setting cursor means we are reserving memory of MB. You system may crash at some point. We can set the limit to , provided the server can handle this much of memory. June 24, - pm UTC. With each call to this function the number of open cursors increased and leads to ORA error. Here is the part of the code used for cursor handling. September 06, - am UTC. Hi, Tom, I found that your query: select a. Thanks Tom! Database version is 10gR1 and parameter is set to March 17, - pm UTC.
Is this possible? March 22, - pm UTC. Sorry, I just realised that is a function we wrote. It just returns the value for the statistic 'opened cursors current'. March 23, - am UTC. As you say above The query [snip] gives you the actual number of truely open cursors. March 23, - pm UTC.
